Write down your calculations, even if you use your calculator. There are 10 problems on 8 pages, including this page. I: find the domain of each function. _________________________: f(x) vx+3 x 2 + 2x - 8 lb. ________________________: let h(x) g(x) from x = 1 to x = 3. __________________________: find an equation of the linear function whose graph is the line containing the point (2, -2) perpendicular to the line y = -x + 1. ________________________: consider the function whose graph is shown below. Give the approximate interval(s) upon which f exhibits the property. __________________________: 6 - in (2t + 4) ________________________: a colony of bacteria is growing exponentially. Initially there are 1000 bacteria in the colony. After 4 hours, there are 5000 bacteria present. Assume that the growth is continuous: give an explicit formula a(t) that gives the population of the colony after t hours. __________________________: after how many hours will the population be 100,0007.
